Study of variations in the male and female glottal wave.

A reflectionless metal tube which can act as a pseudoinfinite termination of the vocal tract was used to collect glottal volume-velocity waveforms produced by 10 male and female adult subjects. From each subject glottal volume-velocity samples were collected of normal, loud, and soft voice; falsetto and creaky voice; monosyllables with rising and failing intonation; and three-syllable utterances containing primary lexical stress on one of the three syllables. Analysis of the data indicates a wide variation of the glottal waveform shape, its rms intensity and fundamental frequency, phase spectrum, and intensity spectrum. It is observed that as the fundamental frequency changes over time, the glottal source varies in one of two different ways. In one type of change, the harmonic relations in the glottal spectrum become steeper as fundamental frequency rises. In a different type of glottal-wave change, relations between harmonics tend to remain the same despite a change in the fundamental frequency; the source spectrum in this case is simply shifted along the frequency and amplitude axes as a function of fundamental frequency. To account for these variations in the glottal source, at least three factors must be known: the sex of the speaker, the voice register in which he phonates, and the linguistic context in which the phonation occurs.

Second formant transitions of selected consonant-vowel combinations in the speech of deaf and normal-hearing children.

Although it is well known that the speech produced by the deaf is generally of low intelligibility, the sources of this low speech intelligibility have generally been ascribed either to aberrant articulation of phonemes or inappropriate prosody. This study was designed to determine to what extent a nonsegmental aspect of speech, formant transitions, may differ in the speech of the deaf and of the normal hearing. The initial second formant transitions of the vowels /i/ and /u/ after labial and alveolar consonants (/b, d, f/) were compared in the speech of six normal-hearing and six hearing-impaired adolescents. In the speech of the hearing-impaired subjects, the second formant transitions may be reduced both in time and in frequency. At its onset, the second formant may be nearer to its eventual target frequency than in the speech of the normal subjects. Since formant transitions are important acoustic cues for the adjacent consonants, reduced F2 transitions may be an important factor in the low intelligibility of the speech of the deaf.

Preparing the nursing profession for participation in a genetic paradigm in health care.

It is critical that nurses be recognized for their ability to deliver genetic services in collaboration with medical geneticists, genetic counselors, physicians, and providers from other disciplines. The purpose of this special communication is to describe progress made by the International Society of Nurses in Genetics toward incorporating genetics into nursing education and practice.

Stress-coping-adaptation: concepts for nursing.

Nursing has arrived at acceptance of several and diverse paradigms in conceptualization of its phenomena, research methodologies, and guidance of the discipline. Scholars and clinicians recognize the interaction of the person with the environment. Some implicitly focus on the experiences of stress, human responses, or efforts to cope with stress and movement toward adaptation or integrity of function. Stress-coping-adaptation is a complex conceptual framework with features powerful enough to explain nursing's phenomena of concern. Discourse dealing with stress-coping-adaptation as integral in nursing theory, research, practice, and education is warranted at this time.

Continuing education for nurses that incorporates genetics.

BACKGROUND: The discoveries of the Human Genome Project are bringing new knowledge of genetics to health and illness arenas. The nursing profession will need to incorporate these new advances into clinical practice, research, and education. METHOD: A survey of 68 nursing specialty organizations was conducted to determine current and future offerings in genetics to members. RESULTS: Responses from 43 organizations' top administrators who are influential in decisions regarding continuing education offerings revealed that 30% were planning to offer content in genetics in future programming. In contrast, none of the respondents had plans to present consumer perspectives of genetic illnesses. CONCLUSION: The results of this survey alert leaders in continuing education to the urgent need for dissemination of genetic advances to inform nurses in basic and advanced roles in health care delivery.

Nursing education and genetics. Miles to go before we sleep.

The discoveries of the Human Genome Project (HGP), established in 1990 at the National Institutes of Health and the United States Department of Energy, are bringing important new technologies for genetic diagnosis and treatment to nearly all areas of health care delivery. Nurses, who play an integral role in supporting health consumers as they respond to health and illness, require up-to-date genetic knowledge for conducting clinical practice, engaging in nursing research, and educating a new generation of nurses.
